5 out of 5 eggsRevised Review

Pros: Features and price.

Cons: None

Other Thoughts: My prior review said the memory slots were bad. Turns out the problem was the CPU. After installing a new CPU (same kind as the first, just a new one) it worked perfectly with all four sticks of RAM installed.

1 out of 5 eggsBad Memmory Slots

Pros: Works great with 1 stick of RAM.

Cons: Will not boot with more than one stick of RAM. I tried another set of RAM, same problem. The first two sets of RAM meet the motherboard specs, but were not on ASUS's QVL list. I got a third set of RAM, which was on the QVL list, but still have the same problem. I have built many computers and servers and am very familiar with installing RAM. I highly doubt the problem was with my installation of the RAM.

Other Thoughts: I have ordered another Z9PA-U8 board, hopefully the new one will work.

Manufacturer Response:

5 out of 5 eggsGreat Hyper-V Server Board

Pros: I have Microsoft Server 2008 R2 Datacenter running on this server board with Microsoft’s Hyper-V supporting 25 virtual machines and 128 Gig of RAM installed. It runs fast and has been in production for over 2 months now with no problems. I also have 2 LSI Raid controllers connected as well. One with 8 Kingston SSD drives in a Raid 6 and another with 8 Seagate 3 TB drives also in a Raid 6 configuration. The optional iKVM works great as well.

Cons: Only wish Newegg carried the ASMB6-iKVM module themselves. I had to order it from another supplier instead.

1 out of 5 eggsNot great, bad QA

Pros: Cheap, holds lots of ram.

Cons: One board had the ram slots fail within 30 days of first use, the second (a different build) came with a bad ram slot out of the box.

When they do work they boot VERY slowly. This has been true of every Asus server board I've ever owned.

Other Thoughts: I bought two of these boards in the past month and a half. The first worked initially and I was happy enough with it.

The day after I ordered a second one of these boards the first one started locking up. After the third restart it stopped booting unless I pulled all but 1 stick of the ram from it. I RMA'd it and started to build my second system. The second board has the same problem. With 1 stick of ram everything is great. As soon as I populate the second slot it will not boot. I have 15 other identical sticks of ram, so I find it highly unlikely that this is a bad piece of ram.

I will definitely return the second board for credit, not a replacement, as at this point I'm pretty convinced this line of boards has a quality control issue. My first RMA should be replaced in the next week and I will have to keep my fingers crossed.
